A review of the most destructive wildfire in Colorado history released Wednesday found much to praise and few problems in the way that Colorado Springs agencies responded.

Investigators say June’s Waldo Canyon fire on the northwest side of Colorado Springs was human-caused, but they still have been unable to determine whether it was intentional or accidental.

The fire left two dead, destroyed 347 houses and charred 28.5 square miles. It prompted evacuations of nearly 29,000 people, according to the review by the city’s Office of Emergency Management.

The report examined only how city agencies responded. It concluded that first responders reacted in an “incredibly professional and heroic manner.”

In one day, police and firefighters evacuated 26,000 people and saved 82 percent of the homes in the area directly affected by the fast-moving fire, the report said.

The report praised the planning and training by city personnel and said agencies cooperated well. It said the city needs better ways to quickly notify other agencies when fire managers make key decisions, and that more personnel should be trained in logistics to support emergency responders.
